CIGARETTE WITH AN IGNITION DEVICE ATTACHED Filed March 6, 1962 "III" INVENTOR TOKUJI NAKAMURA ATTORNEY United States Patent 3,136,318 CIGARETTE WTTH AN IGNETIQN DEVICE ATTACHED Tokuji Nakamura, Asahigawa, Hokkaido, Japan, assignmto Taliashi Fajita, Asahigawa, Hokkaido, Japan Filed Mar. 6, 1962, Ser. No. 177,906 1 Claim. (Cl. 131-3) The present invention relates to a combined cigarette and ignition means and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

The principal object of this invention is to provide an ignition device or cap for each cigarette thereby rendering it unnecessary for the user to carry matches or a cigarette lighter as heretofore has been the custom. Another object is to apply the ignition chemical directly to the outside of the base of the cap and a filter paper insert disposed Within the said cap and in spaced relation to the base.

Another object of invention is to form the cap in such manner that the thick paper portion thereof is capable of being easily removed and discarded after the cigarette is lit.

Another object is the provision of a friction paper attachment for the side of the cigarette box so as to provide an adequate striking surface for the ignition cap.

With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawing forming a part of this application and in which like designating numerals refer to corresponding parts throughout the several views;

FIG. 1 is a perspective view of a case or box especially constructed for the reception and storage of cigarettes in accordance with this invention.

FIG. 2 is a side elevational view of an embodiment of the invention.

FIG. 3 is a section along line A-A FIG. 2.

The cap device designated by the numeral 6 (FIG. 2) is cylindrical in form and designed to slip on the end of a cigarette. One of the ends is closed to constitute a base 3 and this is coated on the outer surface with an ignition producing chemical 4. Inside the cap a filterpaper insert 5 is mounted in spaced relation to the base 3.

The cap 6 is made of thick paper in order to prevent the change of the shape of the tobacco when the cap is picked up.

The filter paper 5 is secured to the inside of the cap by means of a cylindrical flange which alsoserves to space the filter paper from the tobacco of the cigarette.

The quality of the filter paper 5 is the same as that which surrounds the tobacco 7 in the cigarette.

The space between the inside of the base 3 and the filter paper 5 together with the filter paper 5 works to prevent the inhalation of irritating fumes of sulphur and phosphorous or similar compounds which may be either a part of the ignition chemical 4 or result from the combustion thereof.

3,13%,3l8 Patented June 9, i964 The circumference of filtenpaper 5 is affixed to the inside of the cap 6 by means of paste S as shown in FIG. 3.

In use, the ignition cap is slipped on the end of a cigarette and ignition is produced when the base 3 with its chemical coating 4 is rubbed against the friction paper l.

The chemical first fires the base, then the filter paper is ignited and finally the tobacco catches the flame and the cigarette is lit.

The cap 6 is made of thick paper, so there is no fear that the shape of tobacco 7 in the cigarette would be marred when the cap 6 is picked up.

Once the tobacco 7 is lighted, the cap 6 is removed from tobacco 7 and is cast aside.

The filter paper facilitates the ignition of the tobacco and at the same time prevents the direct inhalation of sulfur and phosphorous fumes or compounds thereof resulting from the ignition of the chemical 4 and the friction paper l, at the moment the tobacco catches on fire.

The slip-on ignition cap construction is such as to permit the lighting of a cigarette even in a strong Wind.

While we have described the invention in great detail and with respect to the present preferred form thereof, it is not desired to be limited thereto since changes and modifications may be made therein without departing from the spirit and scope of the invention. The invention may be embodied in other specific forms without departing from the essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claim rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claim are therefore intended to be embraced therein.

I claim:

An ignition device for a cigarette comprising a cap element of thick combustible paper having a base and a cylindrical sleeve adapted to fit on the end of a cigarette, the exterior portion of the base being coated with an ignition producing composition, productive of irritating fumes on ignition, the said cap being provided with a filter paper insert disposed within the cap in spaced relation to the base, the said filter paper insert being provided with a cylindrical inwardly directed flange which functions both to secure the filter paper insert within the cap and space the same from the end of the tobacco of the cigarette, the filter paper insert functioning to prevent excessive inhalation of irritating fumes formed on ignition of the ignition chemical and the base.
